Abstract

The performance of rainwater drainage systems is comingunder ever increasing pressure due to factors such asurbanisation and climate change. With the impact of bothexpected to increase in the future, system capacity willbecome more and more unable to drain the anticipatedincreased volume of rainwater, leading to increased damageand disruption due to flooding. Resilience to these inevitablechanges can only be achieved if current design methods areupdated to enable a “whole system” design approach.This paper assesses the performance of the rainwaterdrainage system of a UK-based case study building throughapplication of a holistic numerical simulation model. Toestablish a baseline of system performance, design rainfallevents were derived from current design standards and usedto drive the model. Differences between the values of eventduration, return period and profile shape as recommendedby the separate design standards are highlighted anddiscussed with the aim of determining appropriate criteriafor whole system design.
